DUST-SCREEN SPECIFICATION forming part of Letters Patent No. 575,937, dated January 26, 1897. Application filed October 13, 1896, SerialNo. 608,702. (No model.)

To all whom, it may concern:

Be it known that I, HUGH BRooKs SHUTrs,

of Shawneetown, in the county of Gallatin and State of Illinois, have invented a new and Improved Dust-Screen for Windows, of which the following is a full, clear, and exact description.

My invention relates to an improvement in dust-screens especially adapted for use in connection with car-windows.

The object of the invention is to provide such a screen which will be simple and economic and readily applied to a window-frame ateither side of the frame and held in position by the window-sash or which may be applied to the outside of the car on the panels between the windows, for example.

A further object of the invention is to so I construct the dust-screen that it will effectually prevent dustand cinders from entering in at an open window when the car is in motion, and, moreover, will cause a gentle draft of air to be produced from the car out through the window where the screen is placed. 7

The invention consists in the novel construction and combination of the several.

parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings,- forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improved dustscreen applied to a windowframe, the window-frame being in vertical section. Fig. 2 is a horizontal section on the line 2 2 in Fig. 1 through the window-frame and the dust-screen applied thereto. Fig. 3 is a vertical section through the windowframe, the dust-screen being shown in front elevation. Fig. at is a face view of an outside panel adapted to receive the screen, and Fig. 5 is a view of a portion of the front of the screen arranged for attachment to the panel.

In carrying out the invention the body A of the screen is of box-like construction, the interior A of the box constituting a dust chamber or pocket. In the detail construction of the box the chamber A is substantially V- shaped or is angular in cross-section, the box comprising a straight inner side 10, inclined outer-side 11, which is connected with the front edge of the inner side, diverging to a predetermined extent from the rear edge of the inner side of the box, and a top 12 and bottom 12, which close the ends of the box. The top and bottom or end portions of the box extend horizontally beyond the corresponding portions of the inner side 10, forming flanges 13. An upright 14 is secured to the forward ends of the flanges 13 and to the front portion of the box A, the upright being provided with a longitudinal rib 15 upon its front face. The rib 15 of the upright is adapted to fit into the sash-groove 16 at either side of the window-frame B, as shown in Fig. 2.

The end portions of the upright let are stepped, the inner longitudinal edge being shorter than the outer longitudinal edge, or the edge which is adjacent to the box, and in each end portion of the upright 14a recess 17 is made of such shape that either recess will receive the bottom rail 18 of the window-sash, as illustrated in Fig. 3. In order that the screen may be readily manipulated and placed in position, a handle 19 is preferably secured to the rear face of the upright 14, as best shown in Fig. 1. i

In both ends of the box an opening 20 is produced, and over-each opening a hood 21 is located, secured to the outer faces of the end portions of the box orbody of the screen. The hoods 21 are of angular shape, their contracted ends being their front ends, and each hood is arched from the end of the box to which it is applied, the rear end of each hood being open, whereby each hood is semiconical in general contour. The openings 20 and the hoods located over them are adapted for the escape of the cinders and dust that may have been conveyed into the dust chamber or pocket A of the device.

In applying the device the window-sash is raised and the rib 15 of the upright 14 is placed in one of the sash-grooves 16, with the contracted or front end of the box facing the engine or forward end of the car. One portion of the bottom of the upright will then be brought to bear on the bottom rail 22 of the window-sash, while the other portion of the bottom of the upright, together with the bottom flange 13, will bear against the belt-rail 23 of the car, as shown in Figs. 1 and 3. The sash is then lowered so that the bottom rail of the sash will enter the upper recess 17 in the upright. The screen will cover a portion of the window-opening, and when the screen is in proper position the opening 20 in the bottom of the body of the screen will be slightly above the bottom rail 22 of the window-sash, while the bottom hood 21 will extend below the belt-rail 23 of the car. As the car moves ahead the dust and cinders striking the inclined face of the body of the screen will be made to diverge from the window, and the dust and cinders that may be drawn toward the window by an eddy will be sucked into the dust chamber or pocket A and will escape through the openings20 in the ends of the chamber or pocket and outthrough the open portions of the hoods 21, being effectually conducted away from the window.

When the screen is applied to the outside of a car, plates are secured in the panels 24 between the windows or at other desired points. These plates cover recesses 26 made in the panel, as shown in Fig. 4c, and each plate has an opening 27, large at the top and narrow at the bottom, the extreme lower ends 28 of which openings are formed as a gutter to facilitate the disposal of rain-water. A dovetail projection 29 is in this instance located at the top and bottom of the upright 14 of the screen, and when these projections are entered into the openings 26 the screen will be securely held in the proper position. The screen with this form of attachment is also reversible.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A dust-screen for car-windows, consisting of a box-body having its outer side inclined outwardly from the front edge of the body, the ends of the body being provided with escape-openings, and hoods located over the escape-openings, being secured to the outer faces of. the ends of the box-body, the said hoods being open at their rear ends and otherwise closed, the box-body being likewise open at its rear end, as and for the purpose set forth.

2. A dust-screen for car-windows, consisting of a box-body angular in cross-section, its rear or expanded portion being open and the ends of the body provided with escapeopenings and hoods located over the outside of the openings, which hoods are contracted at their forward ends and open at their rear or expanded ends, and a fastening device for attaching the screen to a car, substantially as described.

3. A dust-screen for car-windows, consisting of a box body, angular in cross-section and provided at the top and at the bottom with escape-openings, and hoods shaped correspondingly to the box-body, and secured to "the outer faces of the ends of the box over the escape-openings, the box being open at its wider portion and closed at its contracted portion and the hoods having corresponding portions also closed and open, and means, substantially as described, for attaching the screen at either side of a window-frame, as and for the purpose set forth.

i. A dust-screen for car-windows, consisting of a box-body, angular in cross-section and provided at the top and at the bottom with escape-openings, and hoods shaped correspondingly to the box-body and secured to the outer faces of the ends of the box over the escape-openings, the box being open at its wider portion and closed at its contracted portion, and the hoods having corresponding portions also closed and open, an upright secured to the inner front portion of the boxbody, the said upright being provided with a rib upon its forward face, adapted to enter a sash-groove in a window-frame, and the ends of the upright-being recessed to receive the bottom rail of a window-sash, as and for the purpose specified.
